Abstract (en)
[origin: US2004155464A1] A coupling for connection of a tube or hose by pushing-in, comprising a coupling housing formed by two parts (1, 2) which are screwed together or of a single part, said coupling housing containing a clamping ring (6) and a sealing ring (5), for instance an O-ring, where at least the clamping ring is in engagement with an inner conical surface (9) in the coupling housing. A return ring (3) is provided in the coupling, inside of the clamping ring (6) in the direction of insertion of the tube or hose, said return ring engaging, with a conical surface, an inner conical surface (8) in the coupling, oppositely tapered relatively to the conical surface (9) against which the clamping ring (6) is in engagement, and the return ring (3) has a central aperture which is smaller than the external dimension of the tube or hose, and it is expandable, in order to be expanded when the tube or hose is forced through the return ring (3), whereby the engagement against the conical surface (8) will force the return ring (3) to move along the conical surface (8) and thereby also axially, and directly or indirectly, press against the clamping ring (6) in order to force it in the direction of taper of the corresponding conical surface (9).
